Pangani Basin Water Board

Water Resources Data collection

There is an extensive river flow monitoring network in the Basin. The management of data collection activities and maintenance of the network infrastructure are however beset with difficulties but ensure the integrity of the data collected. The management and updating of database performed using different software like HYDATA, MS Access, etc.

The basin has 10 weather stations and 45 rainfall stations which are operational although some of them need replacement of missing/or old instruments such measuring cylinder, thermometers, evaporation pan, etc. apart from that the basin has 59 flow gauging stations plus 15 automatic monitoring devices (Orpheus and Thalimedes data loggers) which are operational although some need replacement of missing or old instruments such as gauge plate, angle iron support, etc due to vandalism, floods, etc. Groundwater monitoring network was not fully covered in the basin where automatic water level recorders have been installed in only 14 boreholes drilled for monitoring water level fluctuation, pressure, temperature, etc.

Data collection primarily recorded by gauge readers or meteorological observers who submit them to the respective basin sub-offices (Arusha, Moshi and Tanga) for further processing, analysis, storage and dissemination at every end of each month. Most of the data are stored in both hardcopy and softcopy such as HYDATA Database.
